I want to render a table in which i will show some info in its caption and other details as its rows. But only caption part is rendering while rows are missing. even that is without any error. How to solve this?? any better way to achieve this???
For above code; i am using:
Backbone.js 1.0.0
MarionetteJS v1.0.3
jQuery JavaScript Library v1.9.1
Underscore.js 1.4.4
there are some basic mistakes: how you should initialize a collection, the correct constructors of backbone objects, etc. Below is a working version of your code.

I have a list view that displays some contents from the api and along side a button that when clicked should show the details of the corresponding item from the list-view on another page, how to associate the button to the specific id and how to present a generic url that accepts these ids to route accordingly. I saw many similar posts but I didn't know how to route those or can't understand how each model is called at that route. Here's my current app, where I've not generalised the routing instead each button is associated to the first id and a route like /1 which takes it to a view to display details of the first element from the collection alone.

I tried this, later, I associated the data-id with the button and gave the model.id I fetched from the api and then got the id on click and then passed the model to be rendered on the detail-view.
Still this doesn't change the router in anyway so still looking for a better way to do it.
Edit
Updated the code and fixed by associating model id with href, and created routes to fetch and get the model from in the router function.
I am trying to retrieve list of object from Server and render it on html using Backbone.js
But facing "- cannot be resolved" error.

Any help/suggestion for this problem is highly appreciated.
It looks like you are mixing Java and Javascript. When you do something like:
<% _.each(products, function(product){ %>
in a JSP file, it gets treated as Java code. However, the code you have inside the <% %> block:
_.each(products, function(product){
is Javascript code.
Since you can't combine the two different languages of Java and Javascript you get a Java error (the JasperException).

Any help would be greatly appreciated.
I figured it out. Looks like a Backbone bug.
When you add the items to the collection it calls Collection.set which first puts all the fetched elements in an array called toAdd. Then it adds from the toAdd collection to the internal models collection but then it triggers the events on the toAdd collection! Therefore the "add" events are triggered in the same order as you received them from the server.
https://github.com/jashkenas/backbone/blob/master/backbone.js#L733
Marionette hooks to the "add" event so it can render the elements and therefore they are rendered in the same order of the toAdd collection which is the order you receive from the server.
So to fix the issue you can pass {reset: true} in the options of the fetch call:
http://backbonejs.org/#Collection-fetch
Thanks,
Boris
Edit: I don't think this is a Backbone bug, I think this is intentional for performance.
Not sure if only writing the model field name as comparator would help. Instead you can write a custom function in comparator something like below:
comparator : function (m1, m2) {
var str1, str2;
str1 = m1.get('firstName');
str2 = m2.get('firstName');
if (str1 && str2) {
str1 = str1.toLowerCase();
str2 = str2.toLowerCase();
if (str1 > str2) {
return 1;
} else if(str2 > str1) {
return -1;
}
}
}
This would sort your collection every time you add/remove a model to the collection or call the collections sort method

Seriously i unable to find my issue here to fix it. as well any one suggest me to find the issue for backbone.js online..
so let me keep check my code..
Thanks in advance..
Pretty sure it is to do with this line in your HTML
<td><%= <a hre="#/edit/<%= user.id %>" class="btn">Edit</a></td>
You open the <%= and then open it again /edit/<%= which I think is causing the problem. Even if opening it twice is allowed, you haven't added a final %> to the line.
Play around with that and let us know how it goes.
EDIT
Try this instead
<td> Edit</td>
You shouldn't need to wrap the entire thing in the <% and %> tags, just the part you want to output.
